Calculation of Current (I)
- As the resistors are connected in series, the current passing through each resistor is the same.
- Total resistance, R_total = R1 + R2 + R3 + R4 = 1 + 3 + 5 + 7 = 16 Ω
- Using Ohm's law, I = V_total / R_total = 20 / 16 = 1.25 A
Calculation of V2
- V2 is the voltage drop across R2.
- As the resistors are connected in series, the voltage drops across each resistor add up to the total voltage.
- V_total = V1 + V2 + V3 + V4
- V1 = I * R1 = 1.25 * 1 = 1.25 V
- V3 = I * R3 = 1.25 * 5 = 6.25 V
- V4 = I * R4 = 1.25 * 7 = 8.75 V
- V1 + V2 + V3 + V4 = 20
- V2 = V_total - (V1 + V3 + V4) = 20 - (1.25 + 6.25 + 8.75) = 3.75 V
Therefore, the correct answer is option B) I = 1.25, V2 = 3.75.
- As the resistors are connected in series, the current passing through each resistor is the same.
- Total resistance, R_total = R1 + R2 + R3 + R4 = 1 + 3 + 5 + 7 = 16 Ω
- Using Ohm's law, I = V_total / R_total = 20 / 16 = 1.25 A
Calculation of V2
- V2 is the voltage drop across R2.
- As the resistors are connected in series, the voltage drops across each resistor add up to the total voltage.
- V_total = V1 + V2 + V3 + V4
- V1 = I * R1 = 1.25 * 1 = 1.25 V
- V3 = I * R3 = 1.25 * 5 = 6.25 V
- V4 = I * R4 = 1.25 * 7 = 8.75 V
- V1 + V2 + V3 + V4 = 20
- V2 = V_total - (V1 + V3 + V4) = 20 - (1.25 + 6.25 + 8.75) = 3.75 V
Therefore, the correct answer is option B) I = 1.25, V2 = 3.75.
