Answer:
The voltage (V)
Explanation:
Ohms, in his law, has explained the relationship between current, resistance and voltage.
Ohm's law, which states that the voltage passing through a resistor is directly proportional to both the current and the resistance of the resistor, has the following equation:
V = IR
Where;
V = voltage (volts)
I = current (Amperes)
R = resistance (ohms)
According to this question, Karl measures the current, I, through a resistor. In order to calculate his resistance, R, he will need to measure the voltage, V.
Answer:
I would make all the people depressed but that would be normal and all the happy people were considerd sped.
Explanation:
Answer: 0.5 seconds or 2.625 seconds
Explanation:
At t = 0, The ball is 4 ft above the ground.
The height of the football varies with time in the following way:
s(t) = -16 t² + 50 t + 4
we need to find the time in which the height would of the football would be 25 ft:
⇒25 = -16 t² + 50 t + 4
we need to solve the quadratic equation:
⇒ 16 t² - 50 t + 21 = 0
⇒ t = 0.5 s or 2.625 s
Therefore, at t = 0.5 s or 2.625 s, the football would be 25 ft above the ground.
Answer:
V = I R
expression does not depend on the frequency, so when changing this quantity does not change the voltage or the current in the circuit.
Explanation:
In a purely resistive circuit, the Ohm relation, m for which
V = I R
We see that the previous expression does not depend on the frequency, so when changing this quantity does not change the voltage or the current in the circuit.
This does not happen in circuits with capacitors or inductors where there is an explicit dependence on frequency.
