Calculate total resistance of resistors connected in series instantly.
Formula: Rtotal = R1 + R2 + R3 + R4
In a series circuit, resistances add directly.
Current remains same, voltage divides across resistors.
| Parameter | Formula |
|---|---|
| Total Resistance | R = R1 + R2 + R3 + R4 |
| Current | Same through all resistors |
What happens in series connection?
Resistances add up.
Where is it used?
Voltage division and circuit protection.
Why use series resistors?
To increase total resistance.
