Answer:

Step-by-step explanation:
V = 
V = 
V = 0.5236
y = 12
Explanation:

We would collect like terms by subtracting 24 from both sides:


The resistance R in ohms (Ω) is equal to the voltage V in volts (V) divided by the current I in amps (A): Since the current is set by the values of the voltage and resistance, the Ohm's law formula can show that: If we increase the voltage, the current will increase.
