Resistance Question with Battery

Question

A wire with resistance R is connected to the terminals of a 30 V battery.

1. What is the potential difference Δ𝑉ends between the ends of the wire?
2. What is the current I through the wire, if the wire has the resistance 1.0Ω?

Answer 1

1) That 30 V represents the potential difference between the two terminals of the battery. That means by definition ΔV = 30 Volts

2) Using Ohm's Law: V = IR. (Voltage or Potential = Current times Resistance)

I = V/R = 30 V / (1 Ω) = 30 Amps

This assumes that there is no internal resistance with the battery itself
