What is the color code for a 220 5% resistor?

• Red, Red, Brown, Gold

• Orange, Orange, Black, Gold

• Red, Red, Black, Gold

• Red, Red, Brown, Silver

Which resistive component is designed to be temperature sensitive?

• Thermistor

• Rheostat

• Potentiometer

• Photoconductive cell

Primary batteries, unlike secondary batteries, may be:

• charged once

• used once

• recharged over and over

• stored indefinitely

In a series–parallel circuit, individual component power dissipations are calculated using:

• individual component parameters

• a percent of the voltage division ratio squared

• total current squared multiplied by the resistor values

• a percent of the total power depending on resistor ratios

The first goal to accomplish in analyzing a complex series-parallel circuit is to

• equate all parallel components

• equate all series components

• solve for all the voltage drops

• solve for the total current and resistance
