Question

A circuit consists of three resistors, R1<R2<R3R1<R2<R3,connected in series to a battery.

A)Rank these resistors in order of decreasing current through them.

B)Rank these resistors in order of decreasing potential difference across them.

Answer #1

(A) since they are connected in series , hence current is equal in all resistors

(B) potential difference across a resistor is given by

Since current , , is equal for all resistor , hence higher is the resistance, R, higher will be the potential difference across that resistor

Since,

Therefore,

1A)Parallel circuit and a battery with three resistors. A switch
is there to prevent current from flowing out. The resistors all
have different resistances such as that R3 is half the resistance
of R1 and R1 is four times the resistance of R2. The switch is
close so the circuit is active. Rank the resistores by the
current going through them, from SMALLEST TO
LARGES.
