Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

Many power supplies come with the ability to switch voltages based on the power input supplied. What are the two voltages that a power supply can switch between?

A	110v and 220v
B	5v and 12v
C	60v and 240v
D	90v and 180v

Explanation:

Detailed explanation-1: -This switch is used to set the input voltage to the power supply to either 110v/115v or 220v/230v.

Detailed explanation-2: -Any component of the appliance that is rated to carry a certain amount of current now has to carry twice that rating and it will dissipate four times as much power as it ordinarily would, and its insulation will scorch or catch fire.

Detailed explanation-3: -Unless you plug in a dual-voltage appliance, plugging a 220-volt appliance into a 110-volt outlet can cause irreparable damage. You can purchase a voltage adapter to get around this problem; they’re easy to find and affordable. Weaker appliances may not immediately die when you plug them into the wrong outlet.

Detailed explanation-4: -Two types of power supplies exist, DC-DC and AC-DC. DC-DC power supplies allow you to plug in electrical devices into car outlets or similar sources that supply direct current, or DC, power. These power supplies are not the most commonly used, though.
