Review

1 Use Ohm's Law to calculate the value of voltage in this circuit if resistance is 70 Ω and current is 10 amps.

85% Answer Correctly

	2100 V
	694 V
	700 V
	1400 V

Solution

Ohm's law specifies the relationship between voltage (V), current (I), and resistance (R) in an electrical circuit: V = IR.

V = \( I \times R \) = \( 10 \times 70 \) = 700 V

Which of the following is the same for each branch of a parallel circuit?

56% Answer Correctly

	current
	resistance
	power
	voltage

Solution

In a parallel circuit, each load occupies a separate parallel path in the circuit and the input voltage is fully applied to each path. Unlike a series circuit where current (I) is the same at all points in the circuit, in a parallel circuit, voltage (V) is the same across each parallel branch of the circuit but current differs in each branch depending on the load (resistance) present.

A diode to an electronic circuit is like a _______________ to a city?

67% Answer Correctly

	parking lot
	one-way street
	traffic light
	highway

Solution

A diode allows current to pass easily in one direction and blocks current in the other direction.

Which of the following can conduct electricity under some conditions but not others?

83% Answer Correctly

	semiconductor
	insulator
	conductor
	resistor

Solution

Semiconductors have valence shells that are exacly half full and can conduct electricity under some conditions but not others. This property makes them useful for the control of electrical current.

The formula specifying Ohm's law is which of the following?

77% Answer Correctly

	\(V = {R \over I}\)
	V = I²R
	\(V = {I \over R}\)
	V = IR

Solution

Ohm's law specifies the relationship between voltage (V), current (I), and resistance (R) in an electrical circuit: V = IR.
