Homework Statement
Can someone please give me insight on how to solve for the total resistance of this circuit? Thank you
To calculate the total resistance in a circuit, you can use Ohm's Law which states that resistance (R) is equal to voltage (V) divided by current (I). Alternatively, you can use the formula R = R1 + R2 + R3... where R1, R2, R3, etc. are the individual resistances in the circuit.
The unit of resistance is ohms (Ω).
In a series circuit, the resistances are connected one after the other, so the total resistance is equal to the sum of all the individual resistances. In a parallel circuit, the resistances are connected side by side, so the total resistance is less than the smallest individual resistance.
No, resistance is a physical property that can never be negative. If you get a negative value when calculating the total resistance, it is likely due to an error in your calculations.
The longer the wire, the higher the resistance, as the electrons have to travel a longer distance. The thicker the wire, the lower the resistance, as there is more space for the electrons to flow. This relationship follows Ohm's Law, where resistance is directly proportional to length and inversely proportional to area (thickness) of the wire.
