Homework Statement
Find voltage across 10 ohm resistor.
Homework Equations
Ohm's law
The Attempt at a Solution
20 // 30 = 12
30 // 60 = 20
That's as far as I can get. The answer is 14.286.
Yup, they did a source transformation (Norton) and then current division.Magnawolf said:
Here's the solution to the problem.
It looks like the book did source transformation, which I didn't think was fair because this problem is before source transformation.
You need more than simple resistor network reductions (parallel/serial) here. Nodal analysis would be a good choice.I know nodal analysis and mesh but I thought it was possible to do without them. I thought you could just find the R-total and then you could find the total current. I guess not?
To find the voltage across a 10 ohm resistor, you can use Ohm's Law, which states that voltage (V) is equal to current (I) multiplied by resistance (R). So, you would need to know the value of the current flowing through the resistor and the resistance value of the resistor.
The formula used to calculate voltage across a resistor is V = I * R, where V is the voltage, I is the current, and R is the resistance.
To determine the current flowing through a 10 ohm resistor, you can use Ohm's Law again, but rearrange the formula to solve for current. So, the formula would be I = V/R. You would need to know the voltage across the resistor and the resistance value.
Yes, you can use a multimeter to measure the voltage across a 10 ohm resistor. Set the multimeter to the voltage setting and place the probes on either side of the resistor to measure the voltage.
The voltage across a 10 ohm resistor is dependent on the current and resistance values, so it can affect the overall circuit in terms of power dissipation and voltage drops. The voltage drop across the resistor can also affect the voltage at other points in the circuit.
