# Ideal Independent Sources

**1) Ideal Independent Voltage Sources**

An ideal independent voltage source is a two-terminal circuit element where the voltage across it

a) is independent of the current through it

b) can be specified independently of any other variable in a circuit.

There are two symbols for ideal independent voltage source in circuit theory:

# Problem 1-15: Power of Independent Sources

Determine the power of each source.

a)

b)

**Solution**

a) The current source keeps the current of the loop and the voltage source keeps the voltage across the current source as shown below.

# Problem 1-14: Current of A Voltage Source

Find the current passing through the voltage source:

a)

b)

**Solution**

a) The voltage source is in series with the current source. Since by definition a current source keeps the current passing through itself constant and the voltage source is in series with the current source, it should have the same current .
