Two resistors of 20 Ω and 30 Ω are connected in the electrical circuit. a, Calculate the total resistance in the electrical circuit if the resistors are connected in series. b, Calculate the total resistance in the electrical circuit if the resistors are - The bulbs
The bulbs are connected serially to two bulbs and one resistor. Each bulb has a resistivity of 100 ohms and a resistor of 60 ohms. The voltage source in the circuit is 24 volts. Do you know what voltage to measure on individual appliances?
- Resistance - ohms
If the resistance of the first resistor is 300 ohms and the resistance of the second resistor is 100 ohms. What is the resulting resistance? - Resistance 5713
The kettle is connected to a voltage of 230 V. Its resistance is 130 ohms. What is the current flowing through the kettle? - Resistance
Determine the bulb's resistance with the current 200 mA and is in a regular lamp (230V). - Resistors
Two parallel resistors connected in series give the resulting resistance $R1Ω and $R2Ω. Determine the resistance of these resistors.
We apologize, but in this category are not a lot of examples.
