/ 3. The Attempt at a SolutionLooking to solve mistakes to study from homework. Here's what I had so far[/B]
Aren't the currents going in the same direction, though? - They're both moving in a clock-wise direction?magoo said:The batteries are arranged in opposite polarity. Check your second equation.
Sum of potential changes (gains and drops) should be zero.Kelsi_Jade said:Because your overall voltage of the loop should end up =0?
Usually, you can't predict that. You should assume the directions of currents first and solve the KVL and KCL equations. If the current direction assumed is incorrect, you'll get a minus sign in the answer.Kelsi_Jade said:If you start with 10V and on the opposite side is 5V, is it bc of Kirchhoff's voltage law that the voltage drop would be negative over the 2kOhm to 5V battery
The formula for finding the current flowing through a resistor is I = V/R, where I is the current in amperes (A), V is the voltage in volts (V), and R is the resistance in ohms (Ω).
To determine the current flowing through multiple resistors in a circuit, you can use Kirchhoff's Current Law (KCL). KCL states that the total current entering a junction is equal to the total current leaving the junction. You can use this law to set up a system of equations and solve for the current through each resistor.
No, the current flowing through a resistor cannot be negative. Current is defined as the flow of positive charge, so it can only have positive values.
The current flowing through a resistor is affected by the voltage across the resistor, the resistance of the resistor, and the type of material the resistor is made of. Temperature can also affect the resistance and therefore the current flowing through a resistor.
Yes, the current flowing through a resistor can change over time. This can be due to changes in the voltage or resistance of the circuit, or due to external factors such as temperature. The current flowing through a resistor can also vary if the circuit contains components that change the current, such as capacitors or inductors.
