الله يوفقكم ويدخلكم الجنه الي يجاوب على اسألتي الفيزلاني

السلام عليكم .....انا أبي حل اسئلة الفيز لاني بصراحه محتاجه حلها وشكرا
وهذه هي الاسئله...جاوبوا على الي تعرفونه بس بسرعه
Ohm's law
Question 1:
Two resistors are connected in parallel and are connected across a 40 volt battery. If each resistor is 1 kilo ohms, what is the total battery current?
Question 2:
a- If ten resistors of equal value R are wired in parallel, what will the total resistance be?
b- How would you combine three 28 ohm resistors to get a total resistance of 42 ohm?
Question 3:
a- Looking at the circuit above, At which position should an ammeter beplaced to measure the current passing only through resistor R1 ?
b- Based on the circuit above, calculate the resistance of R?
c- The diagram below shows a circuit with three resistors connected to a 15 V source. What is the resistance of R2
Question 4:
a- What is the difference between the internal resistance of ammeters and voltmeters?
b- An electric motor draws 150 A of current of current while operating at 240 V. What is the power rating of this motor
