When a tangent line (13.5 cm) and a secant (lines x + 8.45 cm) intersect then:

tangent line^2 = 8.45 * (8.45 + x)

13.5^2 = 71.4025 + 8.45 x

182.25 -71.4025 = 8.45x

8.45 x = 110.8475

x = 13.1180473373

x = 13.1 (rounded)

What is the total resistance of a parallel circuit that has two loads? Load one has a resistance of 10 ohms. Load two has a resi

Romashka-Z-Leto [24]

Answer:

The total resistance is $7.0588\Omega$

Step-by-step explanation:

Attached please find the circuit diagram. The circuit is composed by a voltage source and two resistors connected in parallel: $R_1=10\Omega$ and $R_2=24\Omega$ .

First step: find the total current

For finding the current that the voltage source can provide, you must find the current consumed by each load and then add both. To do that, take first into account that the voltage is the same for both resistors ( $R_1$ and $R_2$ ).
