Four 100-Ω resistors are connected in parallel and this combination is connected across a 100 V supply voltage. Find the power dissipation in each resistor.

Correct option is C

​$$R = 100\Omega, \quad V = 100 \text{ Volt}, \quad P = ?$$

$$i = \frac{V}{R} = \frac{100}{100} = 1 \text{ Amp}$$

$$\text{Power } (P) = v \times i = 100 \times 1$$ $$= 100 \text{ W}$$​​​​
