Explanation:
<u>DC Circuit</u>
The DC circuit shown it the figure has a power source (battery), some resistors, switches and voltage and current meters. The switch S1 is open, so the right branch of the circuit is neglected. Assuming all meters are ideal (no resistive losses), we have a simple series circuit made of resistors R2 and R3.
We are required to compute the total power dissipated in the circuit, which corresponds to the total power delivered by the voltage source.
The power source of V= 6V is delivering a current in the series circuit equal to the current through R1 and R3. That current is the same as that read by M1 known to be I=0.04 A
The power delivered by the source is

Answer:
Tractors are controlled manually (driven manually) most especially in the rural areas but automated when it can be afforded with other machinery attached to it
Robotics and Automation have merged tasks in field eg automated irrigation system
from large sophisticated tools to reduced size ones
Farming productivity and efficiency has changed seriously as a result of automation and robotics as work is being done faster and smarter
