(a) Given,
R = 1 Ω
V = 2 V
Current through 1 Ω = ?
From Ohm's law
V = IR
Substituting the values in the formula above, we get,
2 = I x 1
⇒ I = 2 / 1 = 2 A
Hence, current through Resistor A = 2 A
(b) Given,
R = 2 Ω
V = 2 V
Current through 2 Ω = ?
From Ohm's law
V = IR
Substituting the values in the formula above, we get,
2 = I x 2
⇒ I = 2 / 2 = 1 A
Hence, current through Resistor B = 1 A
