Lesson 6: Solving a circuit with series and parallel resistors

# Finding currents and voltages (mixed circuits)

## Problem

In the circuit shown below, four resistors, R, start subscript, 1, end subscript, R, start subscript, 2, end subscript, R, start subscript, 3, end subscript, and R, start subscript, 4, end subscript, are connected to a cell of voltage, V, equals, 4, space, start text, V, end text.
R, start subscript, 1, end subscriptR, start subscript, 2, end subscriptR, start subscript, 3, end subscriptR, start subscript, 4, end subscript
3, space, \Omega12, space, \Omega8, space, \Omega2, space, \Omega
What is the potential difference, V, start subscript, 4, end subscript, across R, start subscript, 4, end subscript?
V, start subscript, 4, end subscript, equals
start text, V, end text
Stuck?
