Question

If power is 100 watt and voltage is 220 then find resistance

Answer 1

Answer:

Current is simply the rate of flow of charges whereas voltage can be simply defined as the energy that pushes the charges around a circuit. Therefore, the current of that lamp is 5/11 which is approximately 0.45Amps.

Explanation:

Answer 2

Answer:

484 Ω

Explanation:

Hey!

We know that P (Power) = V (Voltage) * I (Current)

Using Ohm's Law we know that : V = IR

Hence, I = V/R

Substituting for our Power - Voltage - Current relationship formula, we get :

P = V * (V/R)

Hence, P = V^2 / R

We are given in this scenario that Power = 100 watt and Voltage = 220 watt.

Substituting, we get :

100 = (220)^2 / R

100 R = (220)^2

100 R = 48400

Hence, R (Resistance) = 484 Ω
