Step 1
Given: - $R_1 = 10 \Omega$ - $R_2 = 30 \Omega$ - $R_3 = 40 \Omega$ - $R_4 = 60 \Omega$ - $V = 220 V$ Calculate $R_{eq1}$: $R_{eq1} = \frac{R_1 \times R_2}{R_1 + R_2} = \frac{10 \times 30}{10 + 30} = 7.5 \Omega$ Calculate $R_{eq2}$: $R_{eq2} = \frac{R_3 \times Show moreā¦

Electrical Resistance If two electrical resistors with resistances $R_{1}$ and $R_{2}$ are connected in parallel (see the figure), then the total resistance $R$ is given by $$R=\frac{1}{\frac{1}{R_{1}}+\frac{1}{R_{2}}}$$ (a) Simplify the expression for $R$ (b) If $R_{1}=10$ ohms and $R_{2}=20$ ohms, what is the total resistance $R ?$
