The voltage in the resistor is 63 V
Explanation:
We can solve the problem by applying Ohm's law, which states the relationship between voltage, current and resistance in a resistor:
[tex]V=RI[/tex]
where
V is the voltage
R is the resistance
I is the current
For the resistor in this problem, we have:
I = 0.42 A is the current
[tex]R=150 \Omega[/tex] is the resistance
Substituting into the equation, we find the voltage needed:
[tex]V=(0.42)(150)=63 V[/tex]
