Calculating Resistance from Current and Voltage Step 1 Write down all of the information that the problem gives you. Most simple physics problems that ask you to calculate resistance give you values for current
Resistors are used in the circuit to limit/resist the flow/passage of electric current through a specific branch. Answer and Explanation: Given data: The voltage is, V1=20V. The resistance of the first resistor is, R1=5Ω. The resistance......
In electrical engineering, the most basic parameters are the current, voltage, and resistance. The parameters are related by a law called Ohm's Law. According to the relation, the voltage across two points in a circuit is jointly proportional to the cur...
Calculator and all Formulas Resistance (ohms), current (amps), and voltage (volts) Ohm's Law is the linear proportionality between current and voltage that occurs for most conductors of electricity. A graph of voltage against current is a straight line. The gradient is the resistance. Practition...
Step 2: Use Ohm's Law and the Power Equations to determine an equation to solve for the power with the given information. Substitute Ohm's Law into the Power Equation for the voltage. V=IRP=IV→P=I2R Step 3: Insert the values for the resistance and the...

specific on-resistanceThe voltage-current characteristics of the Schottky barrier diode defined by the diode equation can be obtained by using iteration method and a C++ program. The diode equation is split into two functions and the current density for a specified forward voltage is evaluated at ...
crosses a resistor, which impedes current flow. In a series circuit, the current lessens with each resistor it crosses. In a parallel circuit, the resistors are placed in such a way that they are all receiving the same amount of current. Current and resistance can be calculated using Ohm's...
To determine the voltage I did voltage/number of globes: 24/16 = 1.5V per globe - Not sure if this is correct or not To determine current, I figured out using resistance formulas that the resistance for each set of 8 globes is 15 ohms R = V/I 24/3.2 = 7.5 ohms tota...
