I seem to be having a problem getting this. I can get the first question, it is .65 A. But I can't seem to figure out the potential at point B. I used Vab = I2 * I1 but it still doesn't work.
The trouble here is that ground is NOT the negative terminal. You need to reduce the series-parallel resistor network to its equivalent between A and B. You can then compute the total resistance thereby finding the total current. Once you have that you can easily compute the voltage drop across each resistor.andrevdh said:Point B is effectively connected to the positive terminal of the battery. So I would think that is would be at +15 V with respect to ground.
FunkyDwarf said:i always thought you couldn't get voltage at a point, because its a difference not a specific value
semc said:I tried out the question and found out that the potential at B is 4.88 ohm is that right?
Electric current is the flow of electric charge through a conductor. It is measured in amperes (A) and is represented by the symbol "I".
Direct current (DC) is a type of electric current that flows in one direction, while alternating current (AC) is a type of electric current that alternates in direction. DC is commonly used in batteries and small electronic devices, while AC is used in most household and industrial electrical systems.
Electric current is measured using a device called an ammeter, which is connected in series with the circuit. The ammeter measures the flow of current through a specific point in the circuit and displays the value in amperes.
A circuit is a closed loop that allows electric current to flow through it. It typically consists of a power source, conductors, and load(s). The flow of electric current in a circuit is determined by the voltage of the power source and the resistance of the conductors and load(s).
A DC circuit typically includes a power source (such as a battery or solar panel), conductors (such as wires), and a load (such as a light bulb or motor). It may also include other components such as switches, resistors, and capacitors, depending on the specific application.
