Engineering Physics Semester 1 Final

Front

What happens to the total resistance in a circuit when resistors are added in series?

Back

The total resistance increases.

Front

What type of circuit is formed when there is a break in the path of current?

Back

An open circuit.

Front

What does the slope of an x-t graph represent?

Back

Velocity.

Front

If the slope of a v-t graph is positive, what does it indicate about the object's motion?

Back

The object has positive velocity and positive acceleration.

Front

What does a constant slope on an x-t graph indicate about the object's motion?

Back

The object is moving with constant velocity.

Front

What is the relationship between voltage, current, and resistance in a circuit?

Back

Ohm's Law: V = I * R.

Front

What is the unit of resistance?

Back

Ohm (Ω).

Front

What is the effect of adding resistors in parallel on total resistance?

Back

The total resistance decreases.

Front

What does a flat line on a v-t graph indicate about an object's motion?

Back

The object is not accelerating (constant velocity).

Front

What is the formula for calculating power in an electrical circuit?

Back

Power (P) = Voltage (V) * Current (I).
