Question

If a 100 V power supply is connected in the circuit below, what are the possibly correct readings on the ammeters clockwise from the upper left (A1 thru A7)?

Answer 1

A1 = 10 V

A2 = 10 V

A3 = 10 V

A4 = 0 V

A5 = 10 V

A6 = 10 V

A7 = 10 V

Step-by-step explanation:

The voltage across each ammeter should be the same for each ammeter connected in parallel. Since each ammeter is connected in parallel with the power supply, the reading across each ammeter should be 100 V. Since the actual voltage inputted from the voltage source is 100 V, each ammeter should read 10 V. The only exception is the ammeter connected in series with the other ammeters (A4). Since no circuit or component is connected in series with this ammeter, the reading should be 0 V.
