A) 1 kvs 60 kj
B) 0.5 kw, 30 kj
C) 10 kw, 600 kj
D) none of these
Correct Answer: A
Solution :
Here: V = 250 volt, i = 4 amp, t = 1 minute = 60 sec The power is given by \[-6\times {{10}^{6}}C,\] \[2.4\times {{10}^{-3}}\] watt \[2.4\times {{10}^{-9}}N\] The energy consumed is E =power \[1.5\times {{10}^{-3}}N\] time \[1.5\times {{10}^{-3}}N\]You need to login to perform this action.
