Calculating Current Drawn by Electric Iron at 110V Supply Line
- Step 1: Calculate the power of the electric iron using P = VI, where V is the voltage and I is the current drawn.
P = 220V x 3.4A = 748W - Step 2: Use the power calculated in step 1 and the new voltage of 110V to calculate the new current drawn using the formula I = P/V.
I = 748W/110V = 6.8A
Explanation
The current drawn by an electric appliance is directly proportional to the voltage applied to it. This means that if the voltage is reduced, the current will increase to maintain the same power output. In this scenario, the electric iron draws a current of 3.4A from a 220V supply line, which gives it a power output of 748W. If the electric iron is connected to a 110V supply line, the power output will remain the same, but the current drawn will increase to maintain this power output. Using the formula P = VI, we can calculate the power output of the electric iron, and then use the formula I = P/V to calculate the new current drawn at 110V. The new current drawn is calculated to be 6.8A, which is almost double the original current drawn. This increase in current is necessary to maintain the same power output at a lower voltage.
