When 3 resistors of 1 ohm resistance each are connected in series to a 12 volt power supply, the total resistance of the circuit is _______ ohms.
I really appreciate any help with this stuff - it's difficult for me! Thanks
The combined resistance of resistors connected in series is the sum of their resistances. Just add the three resistances.
That's right. 1 + 1 + 1 = __ ohms
The voltage doesn't matter.
4 ohm
To find the total resistance of the circuit when three resistors are connected in series, you need to add the individual resistances together.
In this case, each resistor has a resistance of 1 ohm. So when you connect them in series, you add up the resistances:
Total Resistance = Resistance of Resistor 1 + Resistance of Resistor 2 + Resistance of Resistor 3
Total Resistance = 1 ohm + 1 ohm + 1 ohm
Total Resistance = 3 ohms
Therefore, the total resistance of the circuit is 3 ohms.
I hope that explanation helps! Do you have any other questions?
