If the length is 300 cm and R' equals 100Ω, determine the value of IR'.

1. IR' equals 1 volt
2. IR' equals 2 volts
3. IR' equals 3 volts
4. IR' equals 6 volts

Correct answer: IR' equals 3 volts

Solution

The question lacks sufficient context or details, such as the current (I) or the relationship between I and R'. Assuming Ohm's Law (V = IR), if I = 0.03 A (derived from 300 cm possibly representing 3 mA), then IR' = 0.03 × 100 = 3 volts.
