Question

An electric bulb is connected to a $220V$ generator the current is $0.50A$ What is the power of the bulb?

Answer 1

Step 1: Given data.

Given as

Voltage $\left(V\right)=220V$

Current $\left(I\right)=0.05A$

Step 2: Finding the power.

The voltage and current of a bulb are given, the power is calculated through the derived formula of Power.

And we know that

Power $=$ Voltage $\times$Current

$$\begin{gathered} p=220x0.05 \\ p=22x0.5 \\ p=11W \end{gathered}$$

Thus, the required power is $11W$
