2. STEM A 120 -volt battery is connected to a circuit with 30 ohms of resistance. The current in amperes c flowing through the circuit can be found using the equation \( 30 c=120 \). How many amperes of current are in the wire?

To find the current in the circuit, you can rearrange the equation \( 30c = 120 \) to solve for \( c \). Dividing both sides by 30, we get \( c = \frac{120}{30} \), which simplifies to \( c = 4 \). So, the current flowing through the circuit is 4 amperes! You're working with Ohm's Law here! Just remember, the relationship between voltage (V), current (I), and resistance (R) can be expressed as \( V = I \times R \). It’s like a dance party—no one gets to shine without their partners! In your case, with a 120-volt battery and 30 ohms of resistance, the spotlight is definitely on that 4-amp current!
