Question

Five resistors with resistance R1 = 2.00 Ω, R2 = 5.00 Ω, R3 = 5.00 Ω, R4 = 3.00 Ω, R5 = 3.00 Ω, are connected to a battery with emf = 5.00 V as shown in the figure.

a) What is the current in resistor R1?
b) What is the current in resistor R2?
c) What is the current in resistor R3?
d) What is the current in resistor R4?
e) What is the current in resistor R5?
f) What is the potential difference (absolute value) between the points P and P′?

Answer 1

Req(series) = R1+ R2+R3...+Rn
Req(parallel)
\[\huge 1\over {1/R_1 +1/R_2+1/R_3...+R_n}\]
