The current passes through all the resistors combined in series should be__________.
- A
Same
- B
The sum of the current passes from each resistors
- C
Potential difference over the value of equivalent resistance
- D
Both A and C
The current that flows through each resistor is the same because there is only one path for the current to flow.
a) Same: This option is correct. In a series circuit, the same current flows through all the resistors. This is a fundamental characteristic of series circuits, where there is only one path for the current to follow.
b) The sum of the current passes from each resistor: This option is not correct. In a series circuit, the current is the same at all points, and it does not "pass through" each resistor individually. Instead, the current flows through all the resistors collectively.
c) Potential difference over the value of equivalent resistance: This option is correct. The potential difference (voltage) across a series circuit is equal to the sum of the potential differences across each individual resistor. Although it is not directly related to the value of the equivalent resistance.
The current through the circuit is the same for each resistor in a series circuit and is equal to the applied voltage divided by the equivalent resistance.
The current through each resistor is added when the resistors are combined in parallel
