Main characteristic of series circuit and parallel circuit |
| Answer» Characteristics of series circuits: \tcurrent is the same everywhere (ammeter operation)IT = I1 = I2 =I3\tvoltage is different across different resistancesVT = V1 + V2 + V3 (voltmeter operation)\ttotal resistance is equal to the sum of the resistancesR = R1 + R2 + R3\ta break in the circuit stops all currentCharacteristics of parallel circuits:\xa0\tcurrent is different in different resistances, but the total current is equal to the sum of the currents in all the branchesIT = I1 + I2 + I3\tvoltage is the same across all resistancesVT = V1 = V2 =V3\ttotal resistance is less than the sum of the individual resistancesVT/RT = V1/R1 +V2/R2 + V3/R31/RT = 1/R1 + 1/R2 + 1/R3\ta break in the circuit only stops current in the branch where the break occurs | |
