How to Solve Total Resistance in a Series Circuit
1. Identify the given numbers.
R(1) = 1.0 Ohm
R(2) = 2.0 Ohms
R(3) = 3.0 Ohms
2. Determine the missing or required quantity.
R(total) = ? (for series circuit)
3. List the equation.
R(total) = R(1) + R(2) + R(3)
4. Substitute the given numbers to the equation.
R(total) = 1.0 Ohm + 2.0 Ohms + 3.0 Ohms
5. Solve and interpret the answer.
R(total) = 6.0 Ohms
Interpretation: The total resistance for the given series circuit is 6.0 Ohms.
What is a Series Circuit?
A series circuit is a simple type of circuit where an electron passes through one or more resistors. A resistor is anything that pulls power from the battery or the cell, just like a light bulb. For easier understanding, look at the attached photo.
