Question

An electric heater is rated $1000W-200V$. Calculate

The current flowing through it.

Answer 1

Step 1: Given data

Power $P=1000W$

Voltage difference $V=200V$

Step 2: To find out the current flowing through the element

The formula for the current through the element is $I=\frac{P}{V}$

$$\begin{gathered} \Rightarrow I=\frac{P}{V} \\ \Rightarrow I=\frac{1000}{200}=5A \end{gathered}$$

Thus, the current flowing through the element is$5A$.
