Question

how do you find current with only resistance? For example what are the currents of a hot plate with a resistance of 50 Ω and a microwave with a resistance of 21 Ω

Answer 1

IN THIS WE WILL TAKE THE COMMON P. D

THAT IS THE COMMON VOLTAGE OF 220V OF OUR HOUSE CIRCUIT

SO, AS HERE GIVEN R= 50 OHM

AND V=> 220V

SO CURRENT "I"= V/R

=> I = 220/50

=> I = 4. 4 A
