What are the currents through the series R1-R2 and through R3-R4?Mr.Green said:I am not well familiar with the rules, but I think you should write down your attempts so that someone can help you in solving this problem.
Hint: Use Ohm's law.
Voltage is a measure of the electrical potential difference between two points in a circuit. It is often described as the force that drives electric current through a circuit.
Voltage is measured using a device called a voltmeter, which is connected in parallel to the component or circuit being measured. The unit of measurement for voltage is volts (V).
Resistors are electronic components that are used to control the flow of electric current in a circuit. They are designed to have a specific amount of resistance, which is measured in ohms (Ω).
Resistors can either increase or decrease the voltage in a circuit, depending on their value and placement. They are often used to reduce the voltage to a desired level or to limit the amount of current flowing through a circuit.
The voltage in a circuit can be calculated using Ohm's Law, which states that voltage (V) is equal to current (I) multiplied by resistance (R). The formula is V = IR. Alternatively, voltage can also be calculated using a voltmeter to measure the voltage at different points in the circuit.
