- Thermal energy is produced in a resistor at a rate of 85.3 W when the current is 2.62 A. What is the resistance? Number i UnitsYou are working in a lab where RC circuits are used to delay the initiation of a process. One particular experiment involves an RC circuit with a half-life of t₁/2 life needs to be extended. He asks you to change the resistance of the circuit to make the half-life longer. All you can find in the supply room is a single 35.0 old to extend the half-life of the circuit. Determine the new half-life (in s). = 3.00 s. Your supervisor is concerned that the initiation of the process is occurring too soon and that the half- resistor. You look at the RC circuit and see that the resistance is 26.0 0. You combine the new resistor with theA student connects two resistors with unknown resistance values in series, and notes that the equivalent resistance R = 775 2. She then connects the same two resistors in parallel, and measures the equivalent resistance to be Rp = 155 Q. What are the resistances (in 2) of each resistor? smaller resistance Ω larger resistance Q
- Resistance, R, is defined using R = V/I where V is the potential across a resistor, and I is thecurrent. R is measured in ohms (Ω), where 1 Ω = 1 V/A. The constant you determined in eachequation should be similar to the resistance of each resistor. However, resistors aremanufactured such that their actual value is within a tolerance. For many common resistors, thetolerance is 5% or 10%. Calculate the range of possible values for each resistor. Does the constant in each equation fit within the appropriate range of values for each resistor? Do the resistors follow Ohm’s law? Base your answer on your experimental data.

What is the resistance? Number UnitsThe internal resistance of a high voltage power supply is 24 MO and the output is set so that the potential difference across the output when on open circuit is 4000 V? When a load resistor R₁ is connected across the supply the voltage across R₁ is 3000 V. What is the value of the load resistor?
