A set of differentiated calculations question cards to be printed and shared with students to answer in class. The cards are differentiated from green to amber to red, depending on the level of challenge, with green being most accessible.
The formulae required are Q= I x t and W= V x Q. Includes answers for self or peer marking in class.
Example calculations for students to complete
Green level
1. Find the unknown value
I = ?
Q = 140 C
t = 4 min
Red level
2. If there is a current of 10 amperes in a
circuit for 10 minutes, what quantity of
electric charge flows in through the
circuit?
