In an electric circuit, the free electrons are moving around. Since equal charges repel and opposite charges attract, the electrons move from the negatively charged to the positively charged pole of the voltage source.
Answer:
C
Explanation:
When a ball rolls down a hill, Potential Energy Conversion takes place to Kinetic Energy.
Answer: option B: The resistor has a tolerance of 20%.
Explanation:
Resistors are color coded to identify their value and function. For a 3- Band resistor, reading from the left, first band denotes first digit, second band depicts second digit and third color depicts the multiplier. The absence of fourth band means the resistor has tolerance 20%.
Hence, the correct answer is option B. The resistor has a tolerance of 20%.
Answer:
=8.0 Watts
Explanation:
Power is a ratio of work done over time. The power in an electric circuit is calculated using the following formula:
P=I²R
P is power, I is current, R is resistance
Therefore, Power= 4²ₓ 0.5Ω
=8.0 Watts
Answer:
1 meter for this wave
Explanation:
Amplitude is the height of the wave from the midline to the crest
