## How many amps does a 60 watt light bulb use?

0.54 Amps

## What is the resistance of a light bulb that uses 15 W of power?

Answer Expert Verified. Power = (voltage²) / (resistance) . = 15 volt/amp = 15 ohms .

**What will cause a current through an electrical circuit to decrease?**

The greater the battery voltage (i.e., electric potential difference), the greater the current. And the greater the resistance, the less the current. And an increase in the resistance of the load by a factor of two would cause the current to decrease by a factor of two to one-half its original value.

**Which has more resistance 100 watt bulb or 60 watt bulb?**

A 60-watt bulb has a higher electrical resistance than a 100-watt bulb. Because power is inversely proportional to resistance, when the power is less, the resistance is high.

### Which light bulb has a higher resistance?

Thus, it is proved that the 60W bulb has higher resistance than the 100W bulb.

### Which has less resistance a 100W or 60W?

question_answer Answers(1) For a give voltage V, P is inversely proportional to R. So the 60 W bulb will have more resistance than the 100 W bulb.

**Which has more resistance 100w bulb or 50 watt bulb?**

Answer. 60 Watt bulb has more resistance than 100 Watt bulb. Explanation: In order to light bulb we require current or electricity.

**Which has more resistance 50w or 25w?**

Resistance R = V2/P, where V is the potential difference and P is the power in Watts. So, the more the power, the lower will be the resistance and vice versa. Thus, 25 W bulb will have double the resistance as compared to 50 Watt bulb.

Electric power is related to the brightness of the light bulb. Switching in the resistance means that the larger the resistance, the lower the electric power, and the darker the bulb. Therefore, the greater the resistance, the darker the bulb.

An incandescent bulb’s brightness depends on a whole lot on resistance. The higher the resistance to current in the wiring, circuitry, and bulb, the lower will be the current, lower the power, and lower the brightness. Conversely, lower resistance means more brightness.

**Does brightness depend on resistance?**

The brightness of a lightbulb is given by its power. P = I2R, and so brightness depends on current and resistance. If the bulbs are identical, they have the same resistance. Therefore, when you are asked to rank the brightness of identical bulbs, you are really being asked to rank the amount of current through each.

**What is the disadvantage of connecting bulbs in series?**

The first disadvantage is that, if one component in a series circuit fails, then all the components in the circuit fail because the circuit has been broken. The second disadvantage is that the more components there are in a series circuit, the greater the circuit’s resistance*.

## What is better series or parallel?

Two bulbs in a simple parallel circuit each enjoy the full voltage of the battery. This is why the bulbs in the parallel circuit will be brighter than those in the series circuit. Another advantage to the parallel circuit is that if one loop is disconnected, then the other remains powered.

## What are the advantages of bulbs connected in series?

The main reason bulbs are connected in series is allow allow low voltage bulbs to be powered off a higher voltage source. Mini light string usually have 50 bulbs of 2.5V each. Mini bulbs cannot be made for 120V. If they were in parallel, they would need a low voltage transformer.

**Which is brighter bulbs in series or parallel?**

Bulbs in parallel are brighter than bulbs in series. In a parallel circuit the voltage for each bulb is the same as the voltage in the circuit. Unscrewing one bulb has no effect on the other bulb.

**What is the advantage and disadvantage of series connection?**

We know that the series circuits do not get heated easily….Complete answer:

### What is the advantage of connecting batteries in parallel?

Connecting batteries in parallel increases total current capacity by decreasing total resistance, and it also increases overall amp-hour capacity. All batteries in a parallel bank must have the same voltage rating.

### Does Resistance increase battery life?

High resistance causes the battery to heat up and the voltage to drop. The equipment cuts off, leaving energy behind. Lead acid has a very low internal resistance and the battery responds well to high current bursts that last for a few seconds.

**Can you trickle charge two batteries at once?**

Two Batteries in Parallel, One Charger Batteries connected in series strings can also be recharged by a single charger having the same nominal charging voltage output as the nominal battery pack voltage. The purpose of this wire is to balance the voltage drop evenly across both batteries and each wire during charging.
