Assume that a circuit has four equal resistors connected in parallel.
Further assume that two resistors are removed from the circuit, one at a time.
This action will result in a current
decrease and a voltage increase.
increase and a voltage decrease.
One characteristic of a parallel-resistive circuit made up of resistors
having different values is that the
current is different through each resistor.
current divides equally through each of the resistors.
voltage across each resistor depends on the size of the resistor.
voltage across each resistor is the value of the supply voltage
divided by the number of resistors.
What is the value of voltage across resistor B in the series-parallel
circuit shown in figure 8?
What is the power in a circuit if the current is 5 amperes and the
Magnetism is very important in electricity and electronics.
It is the
basis of operation for devices such as
generators, batteries, and motors.
