Determine V1 and R3 if R1= 8ohms I1= 0.75A, R2=5 Ohms and I2=6A. Note that R2 and R3 are connected in parallel. Thank you.
A resistor is an electronic component that is used to control the flow of electric current in a circuit. It is often made of a material with high resistance, such as carbon or metal, and is designed to reduce the amount of current passing through it.
Resistors work by converting electrical energy into heat. As current flows through a resistor, it encounters resistance, which causes the current to slow down and release energy in the form of heat. This heat is dissipated into the surrounding environment, allowing the current to continue flowing at a reduced rate.
Resistance is measured in ohms (Ω), named after the German physicist Georg Ohm. It represents the amount of resistance a material has to the flow of electrical current.
The resistance of a resistor is affected by several factors, including the material it is made of, its length, its cross-sectional area, and its temperature. The longer and thinner a resistor is, the higher its resistance will be. Additionally, certain materials, such as carbon, have a higher resistance than others, such as copper.
The resistance of a resistor can be calculated using Ohm's Law, which states that resistance (R) is equal to the ratio of voltage (V) to current (I). This can be written as R = V/I. Alternatively, if the voltage and current are known, the resistance can be calculated using the formula R = P/I^2, where P is the power dissipated by the resistor.
