To draw maximum current from a combination
WebbLet's assume a bulb of 100 watts, and an heater of 1000 watts, are connected in parallel across a voltage of 240volts, single phase supply. As per Ohms law I =W /V, so for the bulb it will be 100 /240volts =0.24 amperes, and Heater will draw a current of 1000 /240volts =4.1 amperes, approximately. WebbThe currents obtained in the two cases are respectively 1A and 0.36A . The external resistance is: To get maximum current through a resistance of 2.5 Ω, one can use m …
