The electric power in watts in a direct-current circuit with two resistors and connected
Chapter 3, Problem 86(choose chapter or problem)
Power The electric power P in watts in a direct-current circuit with two resistors \(R_{1}\) and \(R_{2}\) connected in parallel is
\(P=\frac{v R_{1} R_{2}}{\left(R_{1}+R_{2}\right)^{2}}\)
where v is the voltage. If v and \(R_{1}\) are held constant, what resistance \(R_{2}\) produces maximum power?

R_1
R_2
P=vR_1R_2/(R_1+R_2)^2
