The derived unit for voltage is named volt.
Working...
length of wire L = 1.5 m
current I = 7 A
potential difference V = 68 Volt
According to Ohm's Law
V = IR
R = V/I
R = 68/7
R = 9.7 Ω
Answer:
The eyepiece comprises a converging lens that is a magnifying lens. The lens has a short focal length,
This lens magnifies this image.
Explanation:
In lenses such as those in microscopes and telescopes, the objective forms an image with the following features:
1. Image is real
2. Image is diminished in size
3. Also, the image formed is upside-down.
The eyepiece comprises a converging lens that is a magnifying lens. The lens has a short focal length,
This lens magnifies this image.
Answer:
1.925 μC
Explanation:
Charge: This can be defined as the product of the capacitance of a capacitor and the voltage. The S.I unit of charge is Coulombs (C)
The formula for the charge stored in a capacitor is given as,
Q = CV ................... Equation 1
Where Q = charge, C = Capacitor, V = Voltage.
Note: 1 μF = 10⁻⁶ F
Given: C = 0.55 μF = 0.55×10⁻⁶ F, V = 3.5 V.
Substitute into equation 1
Q = 0.55×10⁻⁶×3.5
Q = 1.925×10⁻⁶ C.
Q = 1.925 μC
Hence the charge on the plate = 1.925 μC
