Question

calculate current and heat produced in 10 second when a resistor is connected with 250 volt power supply​

Answer 1

Given-

t = 10 s                               t= time

V= 250 V                          V= Potential Difference

Solution-

According To Ohm's law-

I= V/R                                 I= Current          

I= 250/R                             R= Resistance

E= VIt                                 E= Energy

E= 250 x 250/R x 10

E= 625000/R Joules
