A series of free GCSE/IGCSE Physics Notes and Lessons.

In these lessons, we will
• learn how to determine the voltages, resistances and currents in circuit containing resistors in parallel.
• compare resistors in series and resistors in parallel.

Resistors in Series vs. Resistors in Parallel
The following diagram gives the formulas for resistors in series and resistors in parallel. Scroll down the page for more examples and solutions on how to use the formulas.

Resistors in Series and Parallel


The following video explains the above formulas for voltage, current and resistance for resistors in series and resistors in parallel.



Resistors in Parallel, Calculating Voltage, Resistance and Current
Examples:
1. What is the total voltage gain in the circuit?
2. What is the equivalent resistance of the circuit?
3. What is the total current through the circuit?
4. What is the voltage drop across each resistor?
5. What is the current through each resistor?
