Circuits chapter 3 through 8

What feature is unique to digital multimeters (DMMs)?

• Autopolarity

• Moving pointer

• Iron vane

• Fixed resistor

One ampere is equivalent to:

• One coulomb per second

• One watt per second

• One ohm per second

• One volt per second

Analog meters display readings using:

• A digital readout

• Autopolarity

• A moving pointer

• None of the above

Ohm’s law states:

• I = E × R

• I = E/R

• R = P/I²

• P = I × E

Conductance is measured in:

• Ohms

• Siemens

• Watts

• Volts

Power is measured in:

• Watts

• Amperes

• Volts

• Ohms

In a parallel circuit, total resistance:

• Equals the smallest branch resistance

• Is less than the smallest branch resistance

• Is the sum of all branch resistances

• Equals the largest branch resistance

One horsepower is equivalent to:

• 550 W

• 746 W

• 1 kW

• 1.5 kW

Resistance is measured in:

• Amperes

• Volts

• Ohms

• Siemens

Kirchhoff’s Current Law states (parallel circuits):

• Voltage is constant across branches

• Total current equals the sum of branch currents

• Current is inversely proportional to resistance

• Power is constant
