Question

How long will it take, in minutes, for a transformer to transfer 2.3 X 10^6 J of energy from a 120-V circuit to a 345-V circuit with a current of 1.5 A?

PLEASE HELP

Answer 1

is the 1.5 A current primary or secondary?

Answer 2

Not sure but I think it is prmary

Answer 3

2.3 X 10^6=voltageseconday*1.5amp*timeinseconds

I think the current is seconday.

Answer 4

so it would be 2.3 x 10^6 = 345 V x 1.5 amp x time?
then where would the 120 V come in
