What is AWS load balancing? Should I create multiple ec2 instance with same files?

I am new to AWS. I would like to activate load balancing. I need to know that should I create multipl ec2 instance with the same files? Or only one instance is enough?. What will happen while heavy traffic?

AWS Elastic Load balancer (ELB) is for distributing traffic across multiple EC2 instances. You will be registering the instances with the ELB. Even when instances fail and new instances are added to ELB, the traffic is evenly distributed among the remaining active registered instances. Please see the documentation:
AWS Elastic Load Balancing

If you have only one instance, ELB will send traffic only to that. But, what is the use of ELB then? It serves no purpose to have only 1.

If you need to scale out as the traffic increases, you need to use AWS Auto Scaling :
