Answer explanation

Voltage is in Volts (V), current in Amps (A), and resistance in Ohms (Ω)

What is 42 miliwatts in kilowatts

• 0.0042
• 0.00042
• 4.2e-05
• 4.2e-06

Answer explanation

0.000042 (42 * (10^-3 / 10^3))

If the voltage is 123 milliVolts and the current is 0.005 Amperes. Find the resistance(Ω symbol is not required in the answer).

Kirchhoff's first rule of any junction of several circuit element in an electric circuit is based on the law of conservation of:

• Mass

Power _____ are used to connect a power supply to the bread board.

Does this schematic correctly represent this image?

• True
• False

Where should any IC or pushbutton be placed on the bread board?

• Right side of the bread board
• Left side of the bread board
• Ravine
• Any position on the bread board

Answer explanation

Jupiter is a gas giant made primarily of hydrogen and helium. Unlike terrestrial planets that have solid surfaces, gas giants like Jupiter don't have a well-defined solid surface, allowing them to accumulate more mass in a gaseous form. This composition has allowed Jupiter to grow significantly larger than planets with solid surfaces.

• 2 mm - 4 mm
• 4mm - 6 mm
• 6 mm - 8 mm
• 8 mm - 10 mm

Which of the following is a Short-Circuit?

• A
• B
