So to find R (resistance) you do ohm's law E (volts) over I (current) to find R
So this is 12/30 = 0.4 so the resistance is 0.4

Ibrahim is experimenting with his circuits. He made a circuit using a 12V battery and 6.5 ohm resistor. But then he realized he needs to make his circuit safer, so he randomly added a 1 amp fuse in series

A car battery is a 12V DC source. Typically you will find a fuse that can handle a 7 amp surge to power on the lights in your car. What resistance is that fuse protecting?*'
