Answer 1

Here are the answers to your questions:

**Question 1:** The unit(s) for current is
**Answer:** Amps

**Question 2:** The unit(s) for voltage is
**Answer:** Volts

**Question 3:** The current in a resistor is 3.0 A, and its power is 60 W. What is the voltage?
To find voltage (V), you can use the formula for electric power:
\[ P = V \times I \]
From this, we can rearrange to find voltage:
\[ V = \frac{P}{I} \]
\[ V = \frac{60 \, \text{W}}{3.0 \, \text{A}} = 20 \, \text{V} \]
**Answer:** 20 V

**Question 4:** The correct formula for electric power is
**Answer:** P = V × I

**Question 5:** The unit(s) for power is
**Answer:** Watt
