How much current will an electric heater draw from a 220 volt line if the resistance of the heater is 44 ohms?

25 What is the S.I. unit of Power? 26 A heater coil connected to a 220 V ha a resistance of 150Ω . How long will it take for this coil to heat 1 kg of water from 20^o C to 60^o C, assuming that all the heat is taken up by the water? 28 Potential difference across the end of a wire is 0.6V which carries a current of 8 amperes. Find the resistance of the wire. 29 In the given circuit, calculate the current shown by the ammeter and total resistance of the circuit.
