A geyser in a home that has a power rating of 3,2 kw is connected across a 220 v electric supply. calculate the current drawn from the electric supply, the resistance of the geyser element and the energy consumed after an hour.

Question: A geyser in a home that has a power rating of 3,2 kw is connected across a 220 v electric supply. calculate the current drawn from the electric supply, the resistance of the geyser element and the energy consumed after an hour.

A geyser in a home that has a power rating of 3.2 kW and is connected to a 220 V electric supply will draw a current of I = P/V = 3.2 kW / 220 V = 14.55 A from the electric supply. The resistance of the geyser element can be calculated using Ohm’s law, R = V/I = 220 V / 14.55 A = 15.12 Ω. The energy consumed by the geyser after an hour can be calculated as E = P * t = 3.2 kW * 1 h = 3.2 kWh.
