Which has higher resistance a bulb of 50 watt or of 25 Watt?

Which has higher resistance 50W 220v or 25W?

Under a constant fixed applied voltage V R2>R1 25W bulb has higher resistance. Resistance of 25 W lamp bulb is twice the resistance of 50W lamp bulb.

Which has a higher resistance a 100 W bulb or 25 W bulb and by how many times?

ANSWER: 25W has the highest resistance.

Which has higher resistance of 500 Watt bulb or 2.5 Watt bulb and how many times?

Resistance of 500 W bulb be r and that of 2.5 W bulb be R. Thus, resistance of the 2.5 W bulb is 200 times the resistance of the 500 W bulb.

Which has higher resistance A 50W?

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. Or, R2 = 2R1. Thus, 25 W bulb will have double the resistance as compared to 50 Watt bulb.

Which has more resistance 100w bulb or 60w 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 has more resistance 100 W or 60 W bulb explain?

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 60W or 40W bulb if they operated at the same voltage?

If the voltage of two bulbs is assumed to be the same, the resistance of the bulbs equals to V/100 and V/60 respectively. Thus, it is proved that the 60W bulb has higher resistance than the 100W bulb.

Which has higher resistance A 50w bulb or a 25w bulb and how many times?

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. Or, R2 = 2R1. Thus, 25 W bulb will have double the resistance as compared to 50 Watt bulb.

Which has higher resistance ammeter or Milliammeter?

For a constant voltage , the current through a milliammeter must be lower (in the order of milliamperes) but the current through a ammeter would be higher (in the order of amperes) thus the resistance in milliammeter will be higher.

What is the power of torch bulb rated at 2.5 V and 500ma?

Electricity. A torch bulb is rated at 2.5 volt, 500 mA. Find its (i) power and (ii) resistance. = 1.25 W.
