Question

The electrical energy disputed in the resistor is given by

1. W = VIT 2. W = VIR 3. W = RIT 4. W = RT​

Answer 1

(1) The electrical energy disputed in the resistor is given by W = VIT

Given :

A resistor

To Find :

The electrical energy disputed in the resistor

Solution :

We know, if Q amount of charge flows through a cross-section under the potential difference V, then the amount of electrical work done (W) is given by,

 W = Q × V ---------(i)

We know,

 Current (I) = $\frac{Charge (Q)}{Time (T)}$

or, Charge (Q)  = Current (I) × Time (T)

∴ Q = IT   ---------- (ii)

Putting the value of 'Q' in equation (i), we get

W = VIT

Therefore, the electrical energy disputed in the resistor is given by W = VIT

Answer 2

Answer:

The electrical energy disputed in the resistor is given by W = VIT.

Explanation:

• Resistors have a lot of power. Electrical energy is turned into HEAT energy when a current travels across a resistor.
• The heat generated in a circuit's components, which all have some resistance, is dissipated into the air surrounding the components.

The power dissipated in a resistor can be obtained by Ohm's law as P = V × I,

where V = voltage

and I = current.

So, energy dissipated is given by P x t (time).

W = P x t

But p = VI

So, W = VIT

So, option (1) is the correct answer.
