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

• Red, Red, Brown, Gold

• Orange, Orange, Black, Gold

• Red, Red, Black, Gold

• Red, Red, Brown, Silver

If 60J of energy are available for every 15C of charge, what is the voltage?

• 4V

• 60V

• 15V

• 0.25V

An atom's atomic number is determined by the number of:

• neutrons minus protons

• protons

• electrons

• neutrons

A voltage will influence current only if the circuit is:

• open

• insulated

• high resistance

• closed

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 practical applications, battery voltage:

• is restored as soon as disconnect occurs

• is lowered as the load increases

• may be stored indefinitely

• will be reduced to zero as power is drawn

The negative and positive charge symbols are assigned to the:

• proton and electron

• electron and proton

• atom and nucleus

• electron and element

A voltmeter is used:

• to measure current

• in series with the circuit

• in parallel with the circuit

• to measure coulombs

If the current in a circuit equals 0 A, it is likely that the

• voltage is too high

• resistance is too low

• circuit has a short

• circuit is open
