Homework Statement
Please give me a clue, I don't understand, how to find the magnitude of ##I_{ab}##?
cnh1995 said:What have you tried so far? Are you familiar with KCL?
CWatters said:Have you worked out the voltage on a/b?
askor said:I am stuck. What is KCL? Is it Kirchoff's Current Law?
Have you worked out the voltage on a/b?
How?
An electric circuit is a path through which electric current can flow. It is made up of a power source, conductors, and loads, which are devices that use the electric energy to perform functions.
An electric circuit works by allowing electrons to flow from the negative terminal of the power source, through the conductors, and back to the positive terminal of the power source. This flow of electrons creates an electric current, which can power devices or perform other functions.
There are several different types of electric circuits, including series circuits, parallel circuits, and combination circuits. Series circuits have only one path for the current to flow through, while parallel circuits have multiple paths. Combination circuits are a mix of series and parallel circuits.
AC (alternating current) circuits have a constantly changing direction of current flow, while DC (direct current) circuits have a constant direction of current flow. AC is typically used for long-distance power transmission, while DC is used for smaller devices and electronics.
Voltage (V) is calculated by dividing the amount of electrical energy by the amount of charge. Current (I) is calculated by dividing the amount of charge by the time it takes for the charge to move. Resistance (R) is calculated by dividing the voltage by the current.
