b. In the above diagram, determine the current flowing through each of the LED, if R = 220 ohm and VLED = 1.8 Volts?
To determine the current flowing through each LED, we can use Ohm's Law:
Ohm's Law states that the current flowing through a resistor in a circuit is equal to the voltage across the resistor divided by the resistance:
I = V / R
Where:
I = Current flowing through the resistor (in this case, the LED)
V = Voltage across the resistor (in this case, VLED)
R = Resistance of the resistor (in this case, R = 220 ohm)
Given:
VLED = 1.8 Volts
R = 220 ohm
Substituting the given values into Ohm's Law, we can calculate the current flowing through each LED:
I = VLED / R
I = 1.8 / 220
I ≈ 0.00818 Amps (or 8.18 milliamps)
Therefore, the current flowing through each LED is approximately 8.18 milliamps.
To determine the current flowing through each LED, we can use Ohm's Law, which states that the current (I) flowing through a resistor is equal to the voltage (V) across the resistor divided by the resistance (R).
In this case, the voltage across each LED (VLED) is given as 1.8 Volts and the resistance (R) is given as 220 ohms.
Using Ohm's Law, we can calculate the current flowing through each LED using the following formula:
I = V / R
Plugging in the given values, we get:
I = 1.8 V / 220 Ω
Now we can calculate the current flowing through each LED using a calculator:
I ≈ 0.0082 A
Therefore, the current flowing through each LED is approximately 0.0082 Amperes (or 8.2 milliamperes).
To determine the current flowing through each LED in the above diagram, we need to use Ohm's Law, which states that the current flowing through a conductor is equal to the voltage across the conductor divided by its resistance.
Here's how we can calculate the current for each LED:
1. Identify the voltage source connected to the LEDs. In this case, it is VLED with a voltage of 1.8 Volts.
2. Calculate the equivalent resistance for each LED. Since R = 220 ohms, we can assume that each LED is connected in series with a resistor. Therefore, the total resistance for each branch (LED + resistor) is 220 ohms.
3. Apply Ohm's Law to calculate the current for each LED. Using the formula I = V/R, where I is the current, V is the voltage, and R is the resistance, we'll substitute the values.
For the first LED:
I = 1.8 V / 220 Ω
I ≈ 0.00818 A or 8.18 mA (rounded to two decimal places)
For the second LED:
I = 1.8 V / 220 Ω
I ≈ 0.00818 A or 8.18 mA (rounded to two decimal places)
Therefore, the current flowing through each LED is approximately 8.18 mA.
