EVSE Day 5

Think about materials like rubber or glass.

1 / 10

Insulators allow the free flow of electrical current.

a. True

b. False

Safety practices aim to minimize the risk of electrical accidents and injuries.

2 / 10

Which of the following is NOT a common safety practice when working with electrical systems?

a. Working on live circuits whenever possible

b. Wearing personal protective equipment (PPE)

c. Lockout tagout procedures

d. Using insulated tools

Ohm’s Law is represented by the formula V=IRV = IRV=IR.

3 / 10

What does Ohm's Law state?

a. Power is equal to voltage multiplied by current

b. Current is directly proportional to voltage and inversely proportional to resistance

c. Voltage is directly proportional to resistance

d. Resistance remains constant under all conditions

Use Ohm’s Law (V=IRV = IRV=IR). If RRR is constant and VVV increases, what happens to III?

4 / 10

If a circuit has constant resistance and you increase the voltage, what happens to the current?

Electric current is measured in a unit that represents the flow of charge per second.

7 / 10

What is the basic unit of electric current?

a. Volt

b. Ampere

c. Watt

d. Joule

Overloading a circuit involves connecting more devices than it can safely handle, regardless of the individual power draw.

8 / 10

You can safely overload a circuit by plugging in multiple devices as long as they are not drawing a lot of power.

a. False

b. True

Parallel circuits are designed to provide multiple branches for current.

9 / 10

a. True

b. False

Voltage is sometimes referred to as "electric pressure" in a circuit.

10 / 10

What is voltage?

a. None of the above
