Which statement below is TRUE about the current through the circuit if R1 = 4 ;

Question

Which statement below is TRUE about the current through the circuit

if R1 = 4 ; R2 = 5 and R3 = 7 ?

b. Current is the same everywhere in the circuit.

c. Current is greater in the 4 resistor than in 7 resistor.

d. Current is greater in the 7 resistor than in 4 resistor.

e. Current is greater in the 4 resistor than in 5 resistor.

R1 Q R2 Q R3 Q O a. Current is greater at point B than at point A b. Current is the same everywhere in the circuit. c. Current is greater in the 42 resistor than in 72 resistor. d. Current is greater in the 7 resistor than in 42 resistor. e. Current is greater in the 42 resistor than in 52 resistor.

Explanation / Answer

a) False

because, current is same at point A and B

b) False

because, current is not same in upper and lower branches.

c) False
because, upper branch has high resistance than lower branch.

d) True
because, upper branch has high resistance than lower branch.

e) False
because, 4ohms and 5 ohms are connected in series.

so, the current through them must be the same.
