In a circuit, a 100.-ohm resistor and a 200.-ohm resistor are connected in parallel to a 10.0-volt battery.Determine the power dissipated by the 100.-ohm resistor.
Calculate the current in the 200.-ohm resistor.
Answers
Answer:
current in 200ohm resistor = 0.05A
Explanation:
for current in 200 ohm resistor,
let 'I2' and 'R2' be current and resistance in 200 ohm resistor,
potential difference remains same thorughout the circuit because they are connected in parallel,
we have,
V=10V
R2=200 ohm
I2=?
then by ohm's law,
V=I2*R2
10=I2*200
I2=0.05A
Final answer:
The power dissipated by the 100-ohm resistor is 400 watts. The current in the 200-ohm resistor is 0.05 Amps.
Explanation:
To determine the power dissipated by the 100-ohm resistor, we can use the formula P = I^2 * R, where P is the power, I is the current, and R is the resistance. Since the current is the same throughout a parallel circuit, the current flowing through the 100-ohm resistor is the same as the total current in the circuit. Using the formula P = I^2 * R, we can calculate the power dissipated by the 100-ohm resistor as P = (2.00 A)^2 * 100 ohms = 400 watts.
To calculate the current in the 200-ohm resistor, we can use Ohm's Law, which states that the current (I) is equal to the voltage (V) divided by the resistance (R). In this case, the voltage supplied by the battery is 10.0 volts. Using Ohm's Law, we can calculate the current in the 200-ohm resistor as I = V / R = 10.0 V / 200 ohms = 0.05 Amps.

Voltage difference causes charge to flow from higher potential to that of a lower potential.
What is Potential difference?
This is also known as Voltage difference and it is the difference in electric potential between two points.
V= W/Q
where v is potential difference, w is work done and q is charges.
This allows for charges to flow from higher potential to that of a lower potential.

Answer:
Voltage difference causes charge to flow from higher potential to that of a lower potential.
Explanation:
Voltage Difference:
It is work done per unit charge in moving a charge from one point to another point.
V = Voltage difference
W = Work done
Q = Charge
Then,
unit : Volt or Joule/Coulomb
Flow of charge :
A free positive charge move from a region of higher potential to that of lower potential whereas a free negative charge moves from lower potential region to a higher potential.
Thus, a voltage difference is required for the flow of charge.
