Task 2
- In a circuit under test a resistor, R, is connected in series with a capacitor, C. An a.c. current, (, flows through this RC combination, causing a voltage (V) of 6V to be developed across the resistor, and a voltage (Ve) of BV to be developed across the capacitor. Assuming that V is in-phase with i, and Ve lags VR by 90, draw a vector diagram for this arrangement and then calculate the magnitude of the resultant voltage across the whole RC combination.
- You are measuring the force, F, on an electrical conductor operating in the magnetron of a microwave oven, which is subject to a strong magnetic field. The current may be modelled in three-dimensional space as:
I=31-5j+7k
and the magnetic field as:
B=2i+4j-8k
Determine the force, F, as the cross product of the current vector and magnetic field vector, (ie., find 1x B). Using a 3-dimensional Cartesian axis system, draw all three vectors, or use software to do so. - Using the dot product, determine the angle between the current vector and the magnetic field vector.
