  • Q2. Hjjo Arab and the other
  • Q3. R the rasistance and the 3AM are 6
  • Ans. 

    The resistance and the current are related by Ohm's Law, where resistance (R) is equal to the voltage (V) divided by the current (I).

    • Ohm's Law states that R = V/I, where R is resistance, V is voltage, and I is current.

    • If the resistance (R) and the current (I) are given, you can calculate the voltage (V) using Ohm's Law.

    • For example, if R = 6 ohms and I = 3 amps, then V = R * I = 6 * 3 = 18 volts.
