I have a circuit with a known battery voltage and a known
primary current through the circuit, but the circuit is complex
with multiple IDENTICAL resistors (3 or 4 in this case), how would
I solve for the resistance those resistors?
A battery that has a voltage of 20V is attached to a circuit. A
current of 4A is created in the circuit. What is the resistance of
the circuit? A series circuit with made up of a 12 V battery, a 4Ω
resistor, a 8Ω resistor, and a 12Ω resistor. Calculate the
equivalent resistance of the circuit. B. Calculate the voltage drop
at the 8Ω resistor. A parallel circuit comprised of a 24 V battery
and two 48Ω resistor. Calculate...
Measuring Current and Voltage:
Make a circuit consist of a battery and a bulb. Measure
and record the voltage across the bulb and the current through the
bulb. Now attach another bulb in series. Now record the current
through each bulb and the voltage across each bulb.
6- Does the value of the current through each bulb
(resistor) remain the same as in the previous setup of a single
bulb? Why or why not? Explain in words?
7- Does the...
How will voltage and current behave in a circuit with two
adjacent batteries (battery-battery-bulb-bulb)? How does this
change for two non-adjacent batteries
(battery-bulb-battery-bulb)?
A battery of EMF 10 V and internal resistance 3 Ω is connected to a resistor. If the current in the circuit is 0.5 A, what is the resistance of the resistor? What is the terminal voltage of the battery when the circuit is closed?
A circuit for light bulbs in a car has a battery with a terminal
voltage of 24.5 V. The internal resistance of this battery is 0.66
Ohms. All bulbs have the same efficiency. The first bulb of this
circuit has 15 Ohms and is in series with the battery. After this
there are two branches. One branch has the third bulb with 5 Ohms
and the fourth bulb with 7 Ohms. The third and fourth bulbs are in
series with...
1. In an RC circuit, the battery has a voltage of 12.0V and the
R = 5 MΩ and C= 2.5μF. How long will it take in seconds for the
charge to build up to 22.3 microcoulombs? (Show work please)
2. Richard has a 200 V battery and two metal disks, both with an
area of 0.86 m^2 each and a distance
of 0.240 mm. How much charge in microCoulomb can his capacitor
store? (please show work)
