Voltage, V = IR
Where I is current in Ampere, R is Resistance in Ohms.
V = 9A * 43 Ω
V = 387 V
Parallel circuits allow current to flow even if some paths are cut, because a parallel circuit has more than one current-carrying path through it.
Radio waves have longer wavelengths and lower frequencies than microwaves.
infrared is longer wavelengths and lower frequencies than UV light
