An electric drill operating at 120 volts draws a current of 3 amperes. what is the total amount of electrical energy used by the drill during 1 minute of operation?

= 21600 Joules or 21.6 Kilo joules

Electrical energy is given by the formula  = VIt ;

where V is the voltage in volts, I is the current in Amperes, and t is time in seconds.

Voltage = 120 volts

Current = 3 amperes

Time = 60 seconds or 1 minute

Therefore;

Electrical energy = 120 × 3 × 60

                            = 21600 Joules or 21.6 Kilo joules

the minimum amperage that the current in this wire would have to have so that its weight is completely supported by the magnetic force due to earth's field, assuming that no other forces except gravity act on it
