the simpliest answer to your question is in this example.
example you have to lift a 10 kg of rice, you use a little strength in order to lift it, but if your tying to lift a 50 kg of rice, you will exert much effort and strength in order to lift it. it is similar to the motor. if there is higher load the current will increase in order to satisfy the load required..
