Light bulbs can be used to indicate current flow in a circuit. The brightness of a bulb is proportional to the amount of current passing throw it. The figure shows a battery, a switch, two light bulbs, and a capacitor that is initially uncharged The brightness of a lightbulb is given by its power. P = I2R, and so brightness depends on current and resistance
<h3>What is
current flow?</h3>
A stream of charged particles, such as electrons or ions, traveling through an electrical conductor or a vacuum is known as an electric current. The net rate of electric charge flowing through a surface or into a control volume is how it is calculated. [622 Charge carriers, which can be any of a number of particle kinds depending on the conductor, are the moving particles. Electrons flowing over a wire are frequently used as charge carriers in electric circuits. They can be electrons or holes in semiconductors. Ions are the charge carriers in an electrolyte, whereas ions and electrons are the charge carriers in plasma, an ionized gas.

Answer:
<h2>103 Joules</h2>
Explanation:
In this problem we are required to find the potential energy possessed by the television
Given data
mass of television m = 15 kg
height added above the ground, h= 1-0.3 = 0.7 m
acceleration due to gravity g = 9.81 m/s^2
apply the formula for potential energy we have
P.E= m*g*h
P.E = 15*9.81*0.7 = 103 Joules
Answer: 46.5 m/s
Explanation:
Momentum = mass(m) × velocity (v)
momentum of car = momentum of truck
1210 × v = 2250 × 25
v = 46.5 m/s
Answer:
Unbalanced forces is the correct answer.
