Question

If each resistor in this circuit is 10.0 Ω, and the battery is 30.0 V, what does the first ammeter (A1) read?

Answer 1

first determine the equivalent resistance of the system

then use ohm's law to determine the current of the system with the equivalent resistance

Answer 2

\[R=R_1+R_2\]

Answer 3

THIS is for SERIES

Answer 4

\[\frac{ 1 }{ R}=\frac{ 1 }{ R_1 }+\frac{ 1 }{ R_2}\]

Answer 5

in parallel

Answer 6

change the resistors in AMMETER 2 TO SERIES

Answer 7

THEN ADD THAT RESULTANT RESISTANCE TO THE REST OF THE RESISTORS AND THEN FIND THE CURRENT

Answer 8

THAT SHOULD BE 1.2 AMPERES

Answer 9

ok @lucky0539
