Question:

The circuit to the right consists of a battery (V0 = 15.0 V) and five resistors (R1 = 711.0 ohms, R2 = 482.0 ohms, R3 = 763.0 ohms, R4 = 434.0 ohms, and R5 = 565.0 ohms). Find the current passing through points D, B, and E.

Ohm's Law:

Whenever you see an electrical circuit with one voltage source and a combination of resistors, consider using Ohm's Law to save time. When applying Ohm's Law, we first get an equivalent resistance of the resistor combination. The equivalent resistance is simply the value of resistance that can replace all the resistors in the circuit without changing the value of current. When we have a single resistor R and a voltage V of the supply, we apply Ohm's law to get the series current I by the relationship {eq}I = \frac{V}{R} {/eq}. This relationship describes Ohm's Law.
