Three heaters each rated *250 W, 100 V are connected in parallel to a 100 V supply. Calculate :
the resistance of each heater

Text Solution

AI Generated Solution

To find the resistance of each heater connected in parallel, we can follow these steps: ### Step 1: Understand the relationship between power, voltage, and resistance. The power (P) consumed by an electrical device can be expressed using the formula: \[ P = \frac{V^2}{R} \] Where: - \( P \) = Power in watts (W) - \( V \) = Voltage in volts (V) ...
